just curious if anyone has dyno results or even a review?

 

i want to know as well.. they were supposed to put away most of the competitors cams

 

I'm curious as well. Here are the specs I know of for his SOHC VTEC turbo cam vs Crower's turbo cam:

Rocket's:
274 degrees duration
11.9 mm lift

Crower:
260 degrees duration
10.9 mm lift

In another post, I think Earl was saying how 274 deg. would be too much overlap and with an 11.9 lift, tolerances for piston to valve clearance were going to be tighter. Anyone confirm?

 

I remember hearing that there might be/is a b18b turbo cam in development by Rocket, is that true?

 

supposedly all cars gsr b18b and others all getting cams

 

sweet, thanks viren

 

Rocket makes his cams very big. I have his "small" grind on my B20. They have the lift of a crower 403 and more duration than a 404. Great cams, you cannot argue w/ 20+ tuned peak WHP, with gains accross the board. The man knows what he is doing. These cams are not FI cams, but I will be using them in my turbo setup.

 

Is there any way to tune out the overlap with a cam gear for SOHC's? Or would I just have to ask him to grind out some of the duration?

 

That has to be done in the cam grind. Adjusting overlap can only be done on DOHC motors with adjustable gears.

 

Well, I just ordered a set of his FI cams for my B18C setup. We'll see what happens. He tells me this grind has the same duration of the GSR cam with a tad more lift than the CTR, so it should rip, also says it will be compatable with my ITR spring and tit retainer combo.

 

how much did they run?

 

Got them from Camp1320 here on h-t, he's a dealer and has them on sale right now, 575 shipped as i remember.

 

That is interesting that you ordered a set. When i spoke to rocket they werent supposed to be released for the vtec heads for at least another month or longer. Good luck with them!

 

Thanks Jared , that was a special price for you..

Anyways I am a authorized DISTUBUTOR for eF-1 Racing products.. I have invested what i can in the aid of helping ROCKET perfect the best products out there..

the cams are ready... One of ROCKETS bussiness associates have just recenetly purchased a DYNOJET and are in R&D stages ,trying to squezze extra hp thorugh out the power band without poor driving abilities and wear and tear on vavle train..If im not mistaken Black Nitraite coating will be avail at extra coat..... Not like any other people who are doing it for the $$$$$ and making SERECT and better parts for them selfs, ROCKET will sell you what he developed..There are no secrects with ROCKET. what he knows is what you will know.. check out his webiste at www.eF-1.com

For those of you who do not know ROCKET he is a very RESPECTED H-T member. He is Honest and helps everyone out. ROCKET is a personal friend of mine and Trust me he doesnt need to do this. He has a great Job great family and makes $$$$$ but he does this for the pure enjoyment and satisfaction like all of us and perfectying the best of the best.

 

yea rocket and camp are the shiznit very good sellers and bussiness men, not to mention good friends.
i also sell EF-1 products and Camp1320 products

 

I'm waiting for the FI d16a6 cam to come out...

 

Couldn't have said it better. Paul

 

Opphs sorry guys.. TIMMAY and TURBOD16Z6 and a few others will also be carrying eF-1 race performance products.......

Who cares? Sounds like you guys are all swapping spit together

 

Well this is what Rocket had to say about his S22 cam's overlap:

The S22 won't have too much overlap since the lobe center is pretty wide at 114 degrees. I can't tell how much over lap the Crowers have because they don't give this spec.

Cam jargon is pretty much new to me, so can anyone explain? TIA

 

I would assume S22 would have to mean SOHC and that is why he would be mentioning lobe centers. If you have the opening and closing specs on the Crower, it is easy to calculate. Or even easier might be a phone call to Crower

 

Heres my 0.02 on things.

Rocket Hype and *** Kissing
We are not trading spit (good word play though). The good vibes come from the fact that I try my best to help everyone. And that I appreciate all the help that all of you guys have given me. In fact, I hate referring to anyone who buys stuf from us customers. I look at you guys as all friends.

To Overlap or not Overlap
Here's an area that has much "magazine" technology written about it. The amount of overlap you want to run will depend on your setup. ie how much more exhaust pressure you have than intake pressure (boost). On SOHC cams this is expensive to test as you'll need to have different cams ground to figure this out. What you can do is play with the lash abit and see if the engine likes more duration or less duration. Engines are fairly sensitive to this.

What is an FI Cam
Here is another area of grey. Generally anything less than 280 duration will work good for turbos. Remember, a turbo will exagerate the torque cuve. So if you torque curve is real peaky than your power with a turbo will be even more peaky so it is usually best to get a cam that will give you a flat torque curve for your motor.

Pricing and Availablity of Cams
The M24 drag cams have been run and lobe centers have been optimized so they are available for purchase on a deposit and order basis.

The FI cam has not been run yet and that's why I haven't formally released them.
So if you have any issues with the cams we sent you Jared feel free to contact Camp or I.

Equal Intake and Exhaust Profiles
Many of you will notice that my cams have the same profile on intake and exhaust while most other companies cams have more duration on the exhaust and more lift on the intakes.

It's been my experience that equal intake and exhaust profiles works best in most Honda apps. It must be that Honda properly designed the intake and exhuast flow with the proper relationship.

Springs
It is my opinion that you run stiffer springs in any performance application even with stock cams. If you boost, have a lighter flywheel, run more rpm, make more hp per cylinder etc running more spring tension will make the stuff on top last longer.

Cams and Rockers
Honda cams cannot be thought of seperately from the rockers that they move. The shape (curve of the arc of the swiper pad) of the rocker play a big role in the movement of the valve. If you want more lift on Honda head you'll reach a point where that lift (cam profile) will start to open the valve sooner. That's why FI cams can only have so much lift before it starts to add duration to the valve event. Some modified rockers may be necessary to run higher lift and keep the duration down.

Duration and Lift
It is my philosophy that you should run the least amount of duration that will allow you to run the rpm that you want to run. Less duration allows you to build up compression faster and that's what will make your car go. As for lift you want the valve to open quick and stay open and close quick. Peak lift is not as big of a deal as the when and how long the valve stays open.

For those of you who want big dynos numbers longer duration will get you that but you'll sacrifice some responsiveness.

Peace.

Rocket, everytime I read one of ur posts I feel smarter. as opposed to reading my own posts. umm well

I think i have a question, but im gonna go over to http://www.ef-1.com first and see if i can find the answer.

oh yeh. ok ill just ask it here,

specs on the LS cam- B18A/B18B/B20B/B20Z
L21 --> 262 duration 10.4mm lift. Strong NA, Wild FI (re-grind) (Available for order)

I was reading and it said the duration u list is advertised duration and the duration at 1mm lift is actually 40 less. did i regurgitate that right? I was also looking at the crower 402T's and they have a duration of 234, does ur cam have a 262 compared to their 234 or is there a difference in how yall are rating them? thanks hope i am making sense. im new to cams

Thanks for the post Rocket, you have been really patient and helpful in answering my questions on ef-1.com! These were some of the answers I was looking for.

 

Thanks Rocket.
